Abstract

A pump-probe-type saturation spectroscopic experiment has been performed at 980 nm to measure the homogeneous linewidth of the (Formula presented.) I (Formula presented.) – (Formula presented.) I (Formula presented.) transition and the lifetime of the (Formula presented.) I (Formula presented.) state of erbium embedded into lithium niobate single crystals. There are several non-equivalent Er (Formula presented.) –V (Formula presented.) sites with differently oriented defect structure for charge compensation. These non-equivalent centers differ in their transition energies. Hence, our measurements have been done at two nearby frequencies, addressing groups of erbium ions located at non-equivalent sites. The results are compared with lifetime calculations and measurements found in the literature and with the predictions of our simple model calculation.
